Claim 13:
14. A gas spring-powered fastener driver comprising:
a cylinder;
a moveable piston positioned within the cylinder;
a driver blade attached to the piston and movable therewith between a ready position and a driven position;
a lifter configured to move the driver blade from the driven position to the ready position;
a transmission including an output shaft operatively coupled to the lifter to provide torque to the lifter;
an input coupled to the transmission to provide torque to the transmission;
a first clutch positioned downstream of the input and configured to transfer torque to the output shaft in a single rotational direction; and
a second clutch positioned downstream of the input and operably coupled to the output shaft to limit an amount of torque transferred to the output shaft,
wherein, in response to an application of a reaction torque to the output shaft above a predetermined threshold, torque from the motor is diverted away from the output shaft via the second clutch.
