Claim 0:
1. An apparatus for coupling subsea tubular members, comprising:
(a) an alignment sub adapted to be coupled to a stab, the alignment sub comprising:
(i) a generally cylindrical body having one or more fluid, electric, or fiber optic lines extending therethrough, wherein the generally cylindrical body is adapted to be connected to the stab while the stab is moved in a direction of a longitudinal axis of the stab,
(ii) one or more couplings coupled to at least one end of the alignment sub, and
(iii) an orientation profile disposed on a surface of the alignment sub; and

(b) a corresponding alignment member comprising:
(i) a generally cylindrical body, and
(ii) a profile designed to interface with the orientation profile of the alignment sub, the profile being disposed on an inside surface of the alignment member, and wherein the orientation profile and the profile are configured to couple upon a rotation of the alignment sub relative to the alignment member.
