1. A coupling for joining first and second pipe elements, said coupling comprising:
a first ring attachable to an end of said first pipe element, said first ring defining a first groove extending circumferentially therearound and a plurality of receiving surfaces adjacent to said first groove;
a second ring attachable to an end of said second pipe element, said second ring defining a second groove extending circumferentially therearound and a plurality of receiving surfaces adjacent to said second groove;
first and second segments attachable end to end to surround a central space; wherein:
said first segment comprises first and second keys extending lengthwise along said first segment and projecting toward said central space, said first and second keys being in spaced apart relation, and at least one action surface engageable with a receiving surface of said plurality of receiving surfaces of said first ring and at least one action surface engageable with a receiving surface of said plurality of receiving surfaces of said second ring, wherein engagement between said action surfaces and said receiving surfaces prevents rotation of said first and second pipe elements with respect to one another;
said second segment comprises first and second keys extending lengthwise along said second segment and projecting toward said central space, said first and second keys on said second segment being in spaced apart relation;
wherein when said first and second rings are positioned within said central space, said first and second keys of said first and second segments are respectively engageable with said first and second grooves;
wherein said first segment comprises first and second attachment members positioned at opposite ends thereof, and said second segment comprises first and second attachment members positioned at opposite ends thereof, said first attachment member on said first segment being engageable with said first attachment member on said second segment, said second attachment member on said first segment being engageable with said second attachment member on said second segment for attaching said first and second segments to one another.
