A rotor assembly for a hybrid module includes a rotor carrier, a rotor segment, an end ring, a first spacer, a second spacer, and a compressed spring. The rotor carrier includes a first outer cylindrical surface and a radial surface, and the rotor segment is installed on the first outer cylindrical surface. The end ring is fixed to the rotor carrier and arranged for fixing to an engine flexplate. The first spacer is disposed axially between the rotor segment and the radial surface, and the second spacer is disposed axially between the rotor segment and the end ring. The compressed spring is disposed axially between the end ring and the second spacer to press the first spacer, the second spacer, and the rotor segment against the radial surface for frictional torque transmission between the rotor segment and the rotor carrier.

Transmitting torque from a housing to a drive shaft by configuring contact surfaces between a housing and shaft to increase the transmission of torque. Tools such as drilling tools often require torque to be transmitted from a rotating housing to a driveshaft. This is often accomplished through threaded connections or splines. A threaded connection can be used to transmit torque by allowing two pieces to be securely joined by rotating and tightening to a specified torque. A splined connection can also be used to transmit torque, providing sufficient clearance for one member to slidingly receive the other without rotating and torqueing. A tapered polygon may be used to transmit torque that by virtue of tapering can take up clearances between the torque carrying components. As such, the tapered polygon does not introduce significant stress concentrations into the components.

A torsion bar assembly comprises an input shaft, an output shaft, and a torsion bar that connects the input shaft to the output shaft. An end stop face on the input shaft that co-operates with a respective end stop face of the output shaft to limit an angular deflection of the torsion bar assembly in a first direction away from the neutral position and an end stop face on the input shaft that co-operates with a respective end stop face of the output shaft to limit an angular deflection of the torsion bar assembly in a second direction that opposes the first direction. A first alignment feature is provided at or close to the end of the input shaft nearest the output shaft and a second alignment feature is provided at or close to an end of the output shaft nearest to the input shaft, the first alignment feature facing the second alignment feature across a gap. The alignment features each define respective contact surfaces such that if the input shaft and the output shaft are pressed axially towards each other to close up the gap the contact faces co-operate to set relative angular positions of the input shaft and the output shaft to correspond to a neutral position.
