Abstract
A coupling is provided for interconnecting two tubular parts having opposed ends and shoulders spaced from the ends, and via which force is applicable to urge the opposed ends toward one another. The coupling includes two tubular members defining a longitudinal axis and adapted to coaxially receive the respective parts and to transmit axial force thereto, via the shoulders; a torque isolator assembly including an annulus received against one of the shoulders on one of the members, and generally longitudinal projection means positioned on the one member to block rotation of the annulus relative to the one member, and about the axis; cooperating screw threads on the members adapted to interfit when the members are relatively rotated to make up the coupling; and a pusher surface on the other of the members engagable with the annulus to transmit axial force via the annulus to the one shoulder, when the coupling is made up.
