Why Was the Colony of Aden Under the Jurisdiction of British India?

by heckyeam8

''Prior to 1937, Aden had been governed as part of British India (originally as the Aden Settlement subordinate to the Bombay Presidency, and then as a "Chief Commissioner's province"). Under the Government of India Act 1935 the territory was detached from British India, and was established as a separate colony of the United Kingdom; this separation took effect on 1 April 1937''

This seems like a rather weird happening, what were the reasons for the British administration to put these two separate areas together?

Thanks!

I asked this a year ago, because I too thought it was pretty interesting. /u/Commustar gave a pretty helpful answer which you might want to check out in case you don't get any new answers here.
