A housing, having an outer surface of a predetermined frictional coefficient, is disposed around a portion of a shaft, and is rotatable relative to the shaft An outer magnetic member is disposed on the inner surface of the housing, and an inner magnetic member is attached to the shaft and disposed within the housing. The slip torque is adjusted by varying the amount of surface area exposure between the inner magnetic member and the outer magnetic member.
