A mount for securing an actuator cylinder on a gate valve, wherein the valve has a stem extending through a sleeve on the valve bonnet and the actuator cylinder has a collar mounted on the sleeve. The actuator cylinder is mounted such that it will not rotate on the sleeve. A split ring is mounted in a groove in the outer end portion of the sleeve at the collar. A means mounted on the sleeve extends over the split ring to detain it in mounted position.
