Well, depending on what you're doing, you may require a large fraction of an amp of base current for each transistor and no optocoupler is going to do that and remain happy.

At the very least you'll need one further stage of current amplification between an optocoupler and the transistor.

Also, depending on what you are doing, there might be better devices, a MOSFET for example.
