The invention provides a connection device for a joint shaft in a motor vehicle. The connection device includes an axis of rotation, a first connection area for connecting the connection device to a drive train element, a predetermined breaking region, and a tube region which connects directly to the predetermined breaking region. The connection device has an axial extension in the direction of the axis of rotation, and a radial extension orthogonal to the axis of rotation and is designed, at least substantially, as a tubular hollow body. The predetermined breaking region is arranged between the first connection region and the tube region in the axial direction. A connection area is arranged in the axial direction between the first connection region and the predetermined breaking region.

A shaft-hub connection with a shaft that includes a section with external splines, and a hub that includes internal. The hub with its internal splines is assembled in a positively joined manner with play on the section of the shaft including the external splines. The shaft in the section includes the external splines has a recess regularly inside of the external splines, in which a clamping body is inserted neutralizing the play between shaft and hub.

A valve actuator assembly that include an actuator and an actuator mounting assembly. The actuator mounting assembly may be secured to a valve shaft without the actuator present, and the actuator may be secured to the actuator mounting assembly later. This can make it easier to mount the actuator mounting assembly, especially in cramped spaces. In some cases, the actuator may be wired where it is convenient, and then moved to the actuator mounting assembly and secured to the mounted actuator mounting assembly, sometimes with a simple snap attachment. In some cases, a button, lever or other mechanism may release the actuator from the actuator mounting assembly for easy removal.

Disclosed herein is a tool assembly for use with an energy applicator having a shaft extending along an axis between a proximal end and a distal end. The tool assembly comprises a support structure to support the energy applicator, and a connector assembly arranged to engage and releasably lock the energy applicator to the support structure in a locked state. A drive system is coupled to the support structure and is configured to rotatably drive the shaft of the energy applicator about the axis. The drive system comprises a counterweighted clutch assembly.

A tool for use with a surgical robotic manipulator that comprises an energy applicator including a shaft extending along an axis between a proximal end and a distal end. The shaft has an axial-force receiving surface. A tool assembly comprises a support structure to support the energy applicator, an axial connector assembly arranged to engage and releasably lock the energy applicator to the support structure in a locked state, a drive system coupled to the support structure to rotatably drive the shaft of the energy applicator about the axis, a collet assembly cooperating with the axial connector assembly and configured to apply a force to the axial-force receiving surface of the energy applicator in the locked state, and a reference surface. The force includes an axial component directing the energy applicator proximally into continuous contact with the reference surface in the locked state.

Various embodiments of the teachings herein include an axle receiving arrangement with components that can move in opposite directions and in each case move in the direction of an axle that is received by the arrangement. These components can be part of a tensioning side or a compressing side of the arrangement. The arrangement has at least two components that can be combined with one another and one of said components is in contact with the axle surface participates in a positive-locking and non-positive locking fixing of the axle by the axle receiving arrangement and the other of said components ensures the movability in the direction of the axle. The components in the combined state enclose a gap between on the one hand convex and on the other hand concave curved surfaces.

A coupling for a roller tube of a window treatment system may include a body and/or one or more compliant members. The body may include a bore through a rotational axis of the coupling. The body may be configured to be received within the roller tube of the window treatment system. The body may define an outer surface. One or more compliant members may extend at an oblique angle from the outer surface of the coupling. The one or more compliant members may be configured to engage a smooth inner surface of the roller tube. The use of compliant members may enable a rigid connection of the coupling to the smooth inner surface of the roller tube surface, without the use of fasteners.
