By the way, you would need to deform the torus into the shape of a ring obviously.
Scale X and Z: 1
Scale Y: .25
*Section Radius: .2
*Subdivisions Axis: 50
*Subdivisions Height: 50

*attribute can be found in the channel box inputs for torus.

Another way would be to make an oval curve with the EP Curve tool, a circle, then extrude the curve along the circle with Surfaces>Extrude.
