The elastic supports you have defined will produce a lot of rotational stiffness about the Y axis already. But, if you want to specify a rotational stiffness you could scope a torsional spring to the cylindrical surface at the edge of the hole. You might need to turn on beta features for the torsional spring option to be displayed.
