ABSTRACT:
A torque limiting clutch includes a drive shaft having central rotational axis and a groove, a spring member secured to the drive shaft for rotation with the drive shaft about the central rotational axis, a plate adjacent the spring member and rotatable about the drive shaft, and a retaining clip located within the groove of the drive shaft and engaging the plate to retain the plate on the drive shaft. The plate has a pocket forming an axial-facing first abutment engaging the retaining clip and a radial-facing second abutment located outward of the retaining clip to prevent release of the retaining clip from the groove.
