Conjunx Endura
From MediaWiki

A Conjunx Endura is a Transformer's significant other, an individual that he loves. In human terms, a Conjunx Endura would be considered legally a spouse. For example, when the life of a Transformer is threatened to the point of unconsciousness, it falls upon his Conjunx Endura to make medical decisions on his behalf.
Some Transformers think close relationships like these are embarrassing.
