On the bottom of the limb there's a sort of upside-down monorail. The gear teeth are cut into the bottom of it, but it's the parallel sides of the rail we're interested in. The barrel of the index has a long slot that fits over the rail. There's just enough room between slot and rail to avoid friction. The slot is long enough to also prevent any twist or yaw in the index.
The Tamaya gets the same effect with two rollers that fit into a groove in the bottom of the limb.
