A torque transmission shaft is configured having increased coupling strength between end joints and a cylindrical member to achieve high transmission torque. Misalignment and disengagement of outer collars (connection members) is effectively prevented in the step of press fitting the torque transmission shaft to another component, such as a constant velocity joint. Circlips are fitted in annular grooves formed in the end joints. The circlips abut and lock the outer collars. The outer collars each include a smaller diameter portion, and an end surface of the smaller diameter portion includes a plurality of hollow portions. The hollow portions allow a clearance between a serrated portion and the smaller diameter portion to communicate with the exterior of the outer collar. Air bubbles contained in an adhesive are allowed to escape out of the clearance through the hollow portions, and thus the clearance is filled with the adhesive densely.

A locking mechanism for a driveshaft disconnect coupling includes an input jaw member defining a rotation axis, an output jaw member connectable to the input jaw member for common rotation with the input jaw member, and a cartridge assembly. The cartridge assembly is fixed to the input jaw member, includes a pin, and defines a pin movement axis. The pin is movable along the pin axis between a radially inner position and a radially outer position, the pin being disengaged from the output jaw member in the radially inner position and the pin being engaged to the output jaw member in the radially outer position.

A torque transfer system includes a drive shaft threaded into a housing. The drive shaft includes shaft splines. The housing includes housing splines. A sleeve includes inner splines and outer splines. The inner splines are configured to interlock with the shaft splines and the outer splines are configured to interlock with the housing splines.

An adapter is provided which allows an external driving tool to drive a driven tool such as an intraosseous needle assembly, where the external driving tool would otherwise be incompatible with the needle assembly. The adapter includes a driver connector having a bore, where the bore is to receive an external driver of the external driving tool. The adapter further includes a driver attached to the driver connector. A cross-sectional shape of the bore is different than a cross-sectional shape of the attached driver. The attached driver includes resilient legs which assist in securing the adapter to the needle assembly. The resilient legs may include protuberances to secure the adapter.

An assembly for a brake booster, for example, an electromechanical brake booster, comprises a motor output shaft of an electric motor, a transmission input shaft of a transmission which can be coupled to the electric motor, and a coupling element for power-transmitting coupling of the motor output shaft to the transmission input shaft. The coupling element has internal toothing which can be operatively connected or is operatively connected to the motor output shaft and to the transmission input shaft, as well as a brake booster with an assembly.

A disc assembly for an agricultural implement includes a mounting assembly having a housing and a rotatable shaft disposed within the housing. The rotatable shaft includes a recess extending along a portion of an axial extent of the rotatable shaft. The recess is formed by an inner surface of the rotatable shaft. The rotatable shaft also includes a first engagement feature formed on the inner surface and a key disposed about the recess. The key is configured to engage an opening of a disc blade to block rotation of the disc blade relative to the rotatable shaft. Furthermore, the disc assembly includes a fastener having a shaft configured to extend through the opening of the disc blade and to engage the recess of the rotatable shaft. The shaft has a second engagement feature configured to engage the first engagement feature to couple the disc blade to the rotatable shaft.

To provide a process cartridge, a drum unit capable of receiving a driving force from the main assembly, and an image forming apparatus including the process cartridge. A cartridge is provided with a movable member having a driving force receiving portion. The movable member moves between an advanced position and a retracted position.

A clutch arrangement having a first coupler mounted for rotation with a first input gear, a second coupler mounted for rotation with a second input gear, and an input-gear selector mounted for rotation with an input shaft and positioned between the first and second couplers. The input-gear selector is movable on the input shaft relative to the first and second couplers. Engagement of the input-gear selector with the first coupler drives rotation of the first input gear with rotation of the input shaft, and engagement of the input-gear selector with the second coupler drives rotation of the second input gear with rotation of the input shaft.
