How does the torus not RIP itself from izzy?
The ISS, and presumably Izzy, rotates as it orbits earth, presenting its "belly" (nadir) to the earth at all times.

The torus assembly is spinning on the end like a propeller, so its axis of rotation must therefore also precess through 360 degrees every 90 minutes.  This seems like it would impart enormous forces on the bearings and torque on the spine of the station.

So how does the torus assembly not precess the entire station around Amalthea, or rip itself apart through gyroscopic forces?
