In a magnetic clutch a rotatable axially transferrable input disc which is part of a magnetic flux path including a magnetic cup in the output structure, engages annular friction surfaces on the output structure when magnetic flux is generated in the flux path by a coil. The friction surfaces are part of a rotatable coil and a magnetic cup attached to the driven shaft about which the input disc rotates freely in the absence of flux. The frictional torque generated by the engagement of the disc and the friction surfaces is proportional to the voltage applied to the flux-producing coil. When the input disc is locked, application of flux results in a braking action on the driven shaft.
