Could it have been due to poor alignment or loose connections in other places or is it due to the amount of torque we were placing on the centre wheel?

Yes, a partial thread should stronger than a full thread in Shear (Depends on a few other factors, but usually it's always stronger). If the sprocket wasn't spaced off of the wheel at all, then you might be running into some other issues.
If the bolts holding the sprockets to the wheel weren't tight, it could cause some issues, especially if the sprocket was allowed to move under load. Poor Alignment could also cause the bolts to see more load then they should, but how much would depend on how bad everything is.
