A coupling for the handle shaft of a power driven implement which permits angular adjustment of a drive head. The coupling clamps two parts of the handle shaft together, preventing rotation of one part and permits the selectable rotation of the other. The coupling comprises a split clamp joining and securely holding the handle parts in abutment with one part of the handle shaft telescopically interconnecting with the split clamp, and the other part of the handle shaft rotatably interconnecting with the split clamp in any one of a plurality of alignments. A releasable fastener permits loosening of the split clamp to allow rotational adjustment of the parts and their retention at a selected orientation.
