Claim 13:
14. The coupling assembly of claim 1, wherein the coupling assembly is reconfigurable among three states including:
a disconnected state in which the lock indicator is in the first lock indicator position, thereby maintaining the actuator in the first actuator position such that the valve is in the closed position and the locking pin is in the retracted position;
a connected/valve closed state in which the lock indicator is in the second lock indicator position to permit movement of the actuator, with the actuator still being in the first actuator position such that the valve is in the closed position and the locking pin is in the retracted position; and
a connected/valve open state in which the lock indicator is in the second lock indicator position to permit movement of the actuator, with the actuator being in the second actuator position such that the valve is in the open position and the locking pin is in the extended position.
