An electromagnetic clutch for motor vehicle drive line applications includes a friction clutch pack, a ball ramp actuator and an electromagnetic coil. The ball ramp actuator includes a pair of circular members having opposed pairs of arcuate recesses receiving load transferring members and a torsion spring which provides a restoring force to return the circular members to their center, disengaged positions. Improved clutch control, particularly during disengagment, is achieved by this ball ramp actuator configuration.
