How do I add facial animation to a standalone follower?

[Guest Irinotecan]

I am having a problem with Devious Devices, the face gag is not lining up and going into the mouth of my followers.  I am seeing the following error in the Papyrus log:

	[ (B201B01F)].Actor.ClearExpressionOverride() - "<native>" Line ?
	[None].zadGagEffect.ClearMFG() - "zadGagEffect.psc" Line 12
	[None].zadGagEffect.OnEffectFinish() - "zadGagEffect.psc" Line 60
[02/05/2016 - 11:11:28AM] ERROR:  (C1056956): Does not have face animation data, and therefore cannot have their expression o.

I'm guessing this is because my followers are standalone and the author did not include the facial animation.  I do have the "Female Facial Animation" mod from Nexus installed, but I do not know if that is what is needed to allow gags to work.  So can anybody help me figure out how to properly animate their faces?

 

Edit:  I am willing to edit their .esp file in the CK or with TES5Edit if that is required.
