Self-centering blind mate fluid coupling

A coupling member for a blind mate fluid coupling, comprising:

• a housing surrounding a longitudinal axis;
• a valve body at least partially extending through the housing, the valve body having an axially extending internal fluid passage;
• a valve member at least partially disposed in the internal fluid passage, the valve member being movable relative to the valve body to open and close the internal fluid passage;
• and
• an alignment mechanism including a movable engagement part that is radially movable in a radial direction relative to the housing and the longitudinal axis, wherein the alignment mechanism is configured to cooperate with the valve body to facilitate at least radial alignment and/or centering of the valve body,
• wherein the engagement part is a ring having an opening through which the valve body extends, the ring having a cupped surface that is adapted to engage a corresponding cupped shoulder surface of the valve body,
• the alignment mechanism further including a second radially floating ring, wherein the engagement part and floating ring are each radially movable and configured to cooperate with the housing and each other to serve as a radially movable stop.
