The coupling device comprises at least two, preferably three, suitably equiangularly spaced-apart engagement members, preferably in the form of ridges, emanating radially from a center axis and having a pair of flanks that mutually form an obtuse angle. A turning tool and an attachment for the same is also disclosed. |
