ABSTRACT:
A fluid coupling device has a male section (20) and a female section (21). Each of the sections has two rotatable ball valve elements (30,31). A docking member (23,24) is mounted on each section to accomodate a misalignment of the flow passageways when the sections are brought together. When the sections are brought together, the ball valves automatically rotate sequentially from flow-preventing positions to flow-permitting positions.
