Patent ID: 6878068

Claim:
A ring apparatus to interconnect first and second shafts for rotation, comprising: a continuous annular member, said member at least partially defining first and second pairs of opposing radial bores, wherein a first axis is defined by said first pair of opposing radial bores and a second axis is defined by said second pair of opposing radial bores are transverse; a first retainer interconnectable to a first side of said annular member, wherein said first retainer and said annular member in combination define one bore of said first pair of opposing radial bores; a second retainer interconnectable to a second side of said annular member, wherein said second retainer and said annular member in combination define one bore of said second pair of opposing radial bores wherein each said retainer forms at least one interface surface with said annular member and wherein for each said interface surface at least one projection formed on one of said retainer and said annular member extends across said interface surface into a mating recess formed within the other of said retainer and annular member.
