You got there first, I was just going to say that there are five different sites listed on TMA as Devil's Quoit (singular) which are either single standing stones, a dolmen and in one case a burial chamber. Only the henge with its several standing stones is called Devil's Quoits. http://www.themodernantiquarian.com/search/site_names/quoit/
