1. 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 configured to provide torque to the transmission;
a clutch positioned downstream of the input and operably coupled to the output shaft to limit an amount of torque transferred to the output shaft and the lifter,
wherein, in response to an application of a reaction torque to the output shaft above a predetermined threshold, torque from the input is diverted from the output shaft via the clutch,
wherein the clutch includes a ring gear and the second stage includes a carrier coupled between the output shaft and the ring gear.
