Just had a look through the parts database and compared the 730d to the 740 and 750 models. The only difference I found is that the 730d has two different alternators listed depending on what options you have in your car. There is a smaller 180A alternator or the 230A alternator that is standard on the 740 and 750 models. Interestingly enough, the parts database shows a 230A alternator while the brochures talk about a 210A alternator?!?
Anyway, as per the pictures below, there is no clutch that can disconnect the alternator from the drive belt...
The 230A alternator (part number 12 31 7 575 347) as found on the 750:
The 230A alternator (part number 12 31 7 573 755) as found on the 740:
The 180A alternator (part number 12 31 7 808 074) as found on the 730d and 230A alternator (part number 12 31 7 808 075) in the fully optioned 730d :
