Abstract
A rotary coupling has an inner part centered on and rotatable about a main axis and having a radially outwardly directed outer surface and an outer part coaxial with the inner part and having a radially inwardly directed inner surface bearing on the inner-part outer surface. The two parts are formed at the surfaces with an annular array of axially extending holes each having an outer half in the outer part and an inner half in the inner part. Respective pins set in the bores angularly couple the inner part to the outer part. Screwthread formations engaged between the inner and outer parts lock same against relative axial movement.
