Claim 0:
1. A decoupler assembly for decoupling an output shaft from an engine, comprising:
a drive shaft;
a hollow shaft having a threaded interior and at least partially disposed within the drive shaft;
an output shaft extending between a first end and a second end, the second end comprising a threaded exterior operably coupled to the threaded interior of the hollow shaft, the output shaft axially moveable between a first position and a second position; and
a retainer selectively operably coupling the output shaft to the threaded interior;
wherein when a driving torque is transmitted from the drive shaft to the output shaft the retainer is not loaded, when an overrunning torque is transmitted below a torque limit the retainer is loaded, and when the overrunning torque reaches the torque limit the retainer uncouples the second end of the output shaft from the engine and the output shaft moves from the first position to the second position.
