1. A blind mate coupling comprising:
a first coupling member including:
a first housing;
a first fluid connector configured to connect to a first fluid conduit, the first fluid connector being fixed in position relative to the first housing; and
a first valve body at least partially extending in the first housing, wherein the first valve body has a first internal fluid passage that is fluidly connected to the fluid connector, wherein the first valve body is radially fixed with respect to the first housing, and wherein the first valve body is angularly pivotable with respect to the first housing; and
a second coupling member including;
a second housing;
a second fluid connector configured to connect to a second fluid conduit, the second fluid connector being fixed in position relative to the second housing; and
a second valve body at least partially extending in the second housing, wherein the second valve body has a second internal fluid passage that is fluidly connected to the second fluid connector, wherein the second valve body is angularly pivotable with respect to the second housing for enabling angular misalignment between the first coupling member and the second coupling member or radially movable with respect to the second housing for enabling radial misalignment between the first coupling member and the second coupling member;
wherein the second valve body is pivotably fixed with respect to the second housing, wherein the second valve body is radially movable with respect to the second housing.
