Abstract
A clutch assembly for transmitting a first torque between a first member and a second member includes a first clutch and a second clutch. The first clutch is disposed between the first member and the second member and has a predetermined design torque. The second clutch is disposed in series with the first clutch between the first member and the second member and has a predetermined holding torque that is less than the predetermined design torque. The second clutch allows rotation between the first member and the second member when the first torque is greater than the predetermined holding torque.
