Abstract
A torque overload coupler for a driveline allows limited free motion. In one embodiment, torque overload protection is provided by a friction slip clutch and tangs formed at the inner perimeter of a clutch plate fit into spaces between lugs defined on a hub to provide a limited range of free motion. In another embodiment, torque overload is provided by a shear pin and free motion is provided by the shear pin fitting into angular spaces between wings of a relatively rotatable hub.
