Bolt torque when clamping plastic or rubber

For torque values, how do you account for instances when the connection involves clamping down on a gasket or a piece of plastic? The rubber and plastic seem to absorb the torque and require you to torque even more to get a tighter connection. In this case, are you potentially overtorquing the bolt? Are there any guidelines on this?

When you are clamping onto plastic, gasket or other material, you torque will never be greater than that which is applied.

The gasket or plastic material is compressing under the axial force created by the torque of the fastener. The material under compression is acting like a spring and compressing some distance.
