ABSTRACT The unitary spring clutch and actuator assembly has a spring clutch subassembly comprising a shaft for supporting two axially spaced input and output drums which are surrounded by a helically wound spring, one end of which is connected to a control sleeve or collar surrounding the spring. The collar has a stop element which coasts with the actuator subassembly to control ro- tation of the collar and hence engagement or disengagement of the spring from the input and output drums. The actuator subassembly includes a fixed frame for supporting an electro-magnetic control device which is adapted to engage and disengage from the stop element. The spring clutch and actuator subassemblies are secured together at one end portion of the shaft, which projects through an opening in the frame and by a retaining member constructed and arranged to engage the tubular shaft and frame. A bearing is interposed between the shaft and frame to facilitate rotation of the shaft relative to the fixed frame.
