A fluid transfer coupler comprises engagement means, such as a frusto-conical flange (16), for releasable engagement with a complementarily shaped fitting, retaining means (18) configured to releasably retain the complementarily shaped fitting, a valve seat (24), valve closure means (22) releasably engageable with the valve seat, a crank member (32),means such as a handle (36) for rotatably displacing the crank member around its rotational axis and a connecting member (26) pivotally connected to the crank member (32) and connected to the valve closure means (22). The crank member (32) is mounted on separate first and second coaxial spindle members (34, 60) which define the rotational axis of the crank member. |
