<p>A tubular pipe helix system (10) includes a coupler (16) which has a sleeve (60 or 70) which is affixed internally or externally of, and in overlapping relationship with, an end (36) of one shaft (12) to create an enhanced wall thickness (W3) thereat and which is to be received in a collar (52) affixed to one end (40) of another shaft (14), with the two shafts able to be connected together by a single bolt (50) extending through the sleeve (60 or 70), the end (36) of the shaft (12), and collar (52) so as to transmit high torque without the need for multiple bolts.</p> |
