A power driven torque tool for turning a socket to set a threaded fastener. A socket drive to drive the socket from its side has a passage through which a key passes. The key is held in a key holder which itself is held against rotation by a bias spring that biases the key away from the socket, and by holding the key holder against rotation also holds the key against rotation. The key can quickly be changed by releasing the spring from the key holder, changing the key, and then reattaching the spring.
