-1- DEVICE FOR COUPLING A PAIR OF RODS Abstract of the Disclosure A coupling is mounted between a valve stem of a valve and a rod of a valve actuator. The rod includes an extension hav- ing a piston member at the end thereof which is received with- in a cylinder member mounted on the end of the valve stem. The extension and piston member thereof define with the cylin- der member a chamber within the cylinder member. Force can be transmitted from the rod to the stem by full insertion of the piston member within the cylinder member. A pressurized gas is contained within the chamber to limit the force transmitted from the rod to the stem when the relative position of the rod with respect to the stem causes the piston member to be locat- ed intermediate of the cylinder member.
