A system includes a downhole tubular and a latch assembly securable to a conveyance that is configured to lower the latch assembly into a central bore of the downhole tubular. The latch assembly includes a tubular body portion, a plurality of latch keys secured to the tubular body portion, and at least one alignment feature secured to the tubular body portion. The system further includes a latch coupling formed on the downhole tubular. The latch coupling includes a plurality of key profiles configured to engage corresponding key profiles of the plurality of key profiles in response to proper angular orientation of the latch assembly with respect to the latch coupling. Additionally, the system includes at least one guide feature configured to rotate the latch assembly to angularly align the plurality of latch keys with the plurality of key profiles in response to contact with the at least one alignment feature.
