Abstract: The present invention relates broadly to an evacuation coupling (10) for connection to a fluid vessel for evacuation of fluid from the vessel. The evacuation coupling (10) comprises a coupling body (14) including an elongate fluid passageway (18) having a fluid inlet (20) and a fluid outlet (22) at its respective opposite ends. The evacuation coupling (10) also comprises an isolation valve (24) mounted within the fluid passageway (18) and designed to control the flow of fluid. The evacuation coupling further comprises a valve actuator (26) operatively coupled to the isolation valve (24) to effect its opening and closure. The evacuation coupling (10) additionally comprises coupling means in the form of a ball locking mechanism (28) designed to releasably couple with the vessel via the receiver (12). The evacuation coupling (10) also comprises a coupling actuator (30) mounted to the coupling body (14) and arranged to co-operate with: 1. the ball lock mechanism (28) to permit its coupling and uncoupling from the fluid vessel; 2. the valve actuator (26) to either i) restrict movement of the coupling actuator (30) with the isolation valve (24) opened and the ball lock mechanism (28) coupled to the vessel to prevent uncoupling of the evacuation coupling (10) from the vessel, or ii) permit coupling of the evacuation coupling (10) to the vessel with the isolation valve closed.
