Claim 17:
18. A method of releasing a connection between first and second valves of a fluid transfer system, the method comprising:
detecting a first shut down condition;
actuating an actuator mechanism that is coupled to the first valve and the second valve with a piston-cylinder assembly to cause the actuator mechanism to selectively and simultaneously close the first and second valves;
detecting a second shut down condition; and
decoupling a coupler from the first valve and the second valve by actuating the actuator mechanism with the piston-cylinder assembly to cause a gate actuator of the actuator mechanism to engage a gate of a breakaway coupler mechanism that, with the gate in a locked position, is engageable with the first valve and the second valve to releasably couple the first valve and the second valve together, wherein the actuator mechanism comprises a safety plate positioned adjacent to the gate when the actuator mechanism is in a connected state to prevent an inadvertent actuation of the gate out of the locked position.
