A coupling includes first and second annular flanges in spaced relation across a gap. At least one resilient element is disposed in the gap in abutting relation to the first and second annular flanges. A first plurality of fasteners extends from the first annular flange, through the at least one resilient element, to the second annular flange, and a second plurality of fasteners extends from the second annular flange, through the at least one resilient element, to the first annular flange. Fasteners in the first plurality of fasteners is disposed in alternating fashion with fasteners in the second plurality of fasteners.
