Abstract
This invention relates to a service coupling for coupling a vehicle to a service port such that one or more services are transferable therebetween. The coupling comprises a plug comprising at least one service engagement portion; and a receptacle comprising an opening to receive the plug, and at least one service engagement portion positioned to engage the plug service engagement portion when the plug is inserted into the receptacle. The engagement is such that a service is transferable between the plug and receptacle. At least one of the plug and receptacle service engagement portions is arcuate thereby enabling engagement to be maintained between the plug and receptacle engagement portions when the plug is rotated about the axis and within the arc-length of the arcuate engagement portion.
