1. A toolless disassembly rotational valve coupling apparatus for manipulation by a user's hands and fingers, the coupling apparatus comprising:
a coupling housing body defining a central aperture, the coupling housing body defining an output seal aperture proximate to an output handle retention slot and slot lip, the slot lip defining a slot handle gap and a slot lip;
an output seal retainer including a coupling handle ring with a first triangulated offset body retention ear, a second triangulated offset body retention ear, a handle offset body retention ear, a first triangulated offset hand graspable handle, and a second triangulated offset hand graspable handle;
the first triangulated offset hand graspable handle and second triangulated offset hand graspable handle separated by a ring handle gap;
wherein the first hand graspable handle and second hand graspable handle can be compressed toward each other to selectively position the first hand graspable handle and second hand graspable handle behind the slot lip;
a seal body positioned in the output seal aperture; and
the seal body defining a seal aperture with a seal axis and a tube lip parallel to the seal axis.
