A flexible coupling for drivingly connecting two rotatable shafts or the like includes a flex member connected between driving and driven members. The flex member consists of four flat arms, arranged to form two Vs with their interior angles facing one another, and a connecting piece connected to and extending between the vertices of the two Vs. Angular and endwise misalignment of the axes of the two rotatable parts joined by the coupling is accommodated by bending of the flat arms out of the neutral plane of the flex member and by twisting of the connecting piece. The flex member is easily fabricated as a one-piece unit by cutting it from a flat sheet of metal or plastic or by forming it through a molding or casting process. The coupling may include only a single flex member or it may have a number of such members connected in series to increase its misalignment capabilities.
