ABSTRACT:
A locking bracket for a valve actuator is disclosed in which a bracket element slips over the rotatable input shaft of the actuator and has an arm extending over the surface of the actuator. A locking plate is affixed to the input shaft which may be interconnected to the bracket element. When so interconnected, rotation of the input shaft is prevented by contact between the arm and the surface of the valve actuator. The locking bracket is easily and economically installed due to the lack of any positive physical interconnection between the bracket and the actuator housing.
