ABSTRACT:
A heavy duty rotary drive coupling is suitable for use in drilling holes in subterranean formations. The coupling includes passages for delivering drilling fluids to and from the bottom of the drill hole, and yet is designed to accommodate axial misalignment and can be rapidly connected and disconnected. The drive coupling is particularly suitable for use in floating drilling platforms.
