1. A single-use aseptic fluid coupling assembly defining a longitudinal axis and an open fluid flow path through the single-use aseptic fluid coupling assembly along the longitudinal axis, the single-use aseptic fluid coupling assembly comprising:
a first coupling comprising:
a first housing;
a first termination member fixedly coupled to the first housing and including a first termination;
a shell that is rotatably coupled to the first housing;
a first valve that is fixedly coupled to the first termination member; and
a shuttle disposed about the first valve, the shuttle being coupled to the shell such that the shuttle is translatable along the longitudinal axis in response to rotation of the shell; and
a second coupling releasably connected to the first coupling and comprising:
a second housing;
a second termination member fixedly coupled to the second housing and including a second termination; and
a second valve movably coupled to the second termination, the second valve being translatable along the longitudinal axis relative to the second termination,
wherein the first housing and the shell comprise a one-way rotation mechanism by which the shell is rotatable relative to the second coupling in only one direction.
