Fused disconnect installation

I bought a 240V fused disconnect at a big box store - no instructions but the innards are clearly marked. My question is this: the terminals for the ground and neutral are electrically connected. That is to say, it looks like I am supposed to tie the neutrals and ground together. This can't be right, can it? I thought it was a no-no to do this (except at the main panel, of course).

No it's not right; they should be separate. Often an insulated neutral bar is not provided in the disconnect because they are used with 240V-only loads (pumps, air cond., etc) which do not require a neutral. If you need to splice neutral in the box, use an insulated connector like a wirenut, Polaris connector, or split-bolt and heavy tape.
