1. An apparatus, comprising:
a stab body;
first and second inlets/outlets;
a flange on an end of the stab body,
wherein the first and second inlets/outlets are positioned adjacent an upper surface of the flange;
a coupler body positioned around the stab body, the coupler body adapted to rotate relative to the stab body;
first and second hydraulic coupling elements positioned on the coupler body;
first and second separate coiled tubes positioned around the stab body;
a first pressure-tight conduit that comprises the first inlet/outlet, the first coiled tube and the first hydraulic coupling element;
a second pressure-tight conduit that comprises the second inlet/outlet, the second coiled tube and the second hydraulic coupling element,
wherein the first pressure-tight conduit is isolated from the second pressure-tight conduit;
a tubing hanger;
first and second hydraulic coupling elements positioned on the tubing hanger,
wherein the first and second hydraulic coupling elements are, respectively, operatively coupled to the first and second hydraulic coupling elements;
a first orientation structure positioned on one of the coupler body or the tubing hanger; and
a second orientation structure positioned on the other of the coupler body or the tubing hanger,
wherein the second orientation structure and the first orientation structure are adapted to engage one another so as to establish a desired relative orientation between the coupler body and the tubing hanger.
