Abstract: An inexpensive torque transmission device is provided which is applicable as either a brake or a clutch and comprises a conical friction element axially slidable between two relatively rotatable members. The element has a friction surface engageable with one of the members and a toroidal tension spring is tensioned between its conical face and the other of the members to exert a yieldable force urging the element into frictional engagement with the first member thereby transmitting a predetermined torque between the two members. The spring also reduces any tendency for the friction element to rotate relative to the second member.
