Claim:
1. An internal connection assembly for use in a rigid flange coupling, the internal connection assembly comprising: a partially discontinuous sleeve comprising a protruding ridge on an outer surface of the sleeve and two tapered surfaces extending from each side of the protruding ridge to the respective, axially spaced apart ends of the sleeve, wherein the sleeve defines an internal cylindrical passage for, in use, receiving an end of a shaft, the partially discontinuous sleeve having at least two partial discontinuities running along the length of the sleeve in the form of two discrete axial slits in the sleeve, wherein the slits are displaced from each other between 2 to 8 mm to form a connecting formation with a width of 2 to 8 mm therebetween; and an inner and outer ring, wherein the outer ring has a partial discontinuity in the form of two partial parallel slits in a side wall of the outer ring, the outer ring slits being displaced from each other thereby to form an outer ring connecting formation.
