Universal joint adapter ring

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 said first and second pairs of opposing radial bores define first and second axes substantially common plane;
• a plurality of retainers interconnectable to said annular member, wherein each said retainer forms a first portion of one of said bores and said annular member forms a second portion of said bore;
• a first abutting surface formed on each said retainer;
• and
• a second abutting surface formed on said annular member, wherein said first and second abutting surfaces abut upon interconnection of each said retainer to said annular member to advancement of said each retainer in a direction perpendicular to said common plane.

• at least one projection integrally formed on one of said retainer and said annular member;
• and
• a mating recess integrally formed within the other of said retainer and said annular member, wherein said projection and recess engage to prevent advancement of said retainer beyond a predetermined position relative to said second portion of said bore defined by said annular member.
