A power transfer pipe, surrounded by an elastomeric, self lubricating seal assembly, transfers rotational power in one direction from a prime mover, at the upper end of the power transfer pipe, to a threadedly secured, hollow, drill pipe at the lower end, the seal assembly directs fluid from the sleeve into the drill pipe. A ratchet assembly at the upper end of the power transfer pipe, facilitates the disengagement of the power transfer pipe from the drill pipe.
