    When it comes to black holes, is there any mechanism that determines which way around the accretion disc is orientated?

    If you had a dozen star & black hole pairs, would the accretion discs of all of them be spinning at the same angle relative to each other?

    They're normal to the axis of rotation, aren't they?
