Could anyone help with this, direct me to written info or explain what the adviser is and does?
According to the latest Handbook 2, chapter 16.1, this position no longer exists. In 16.1.2, the Stake Single Adult Committee, if organized by the stake, may include several single adults, but there is no longer any mention of a single adult advisor.
The stake president does assign a counselor to oversee the work with Single Adults in the stake, and a high councilor may be assigned to assist. That would be the closest thing there is to an "advisor" now.
The Stake
Young Single Adult Committee does include "a couple called to serve as young single adult advisers", along with YSA representatives from each ward. (16.3.2)
The Single Adult organization is decidedly different from the Young Single Adult organization.
