I had the same problem at first.
Based on ext/commerce_coupons/doc/quick_howto.txt and the thread 
"[TYPO3-commerce] commerce_couponss" from last year I chose to use the 
article "syscoupons_use".

Today I found the following text in the top of 
ext/commerce_coupons/static/setup.txt:
######## Note:
# couponNormalType is the Id of the normal coupons, which are money or
   percent
# couponRelatedType is the Id of coupons that have an related article
# couponBuyType is meant as Id if you have coupons that can be bought by
   customer, not in use here at the moment

A little below:
   couponNormalType = 4
   couponRelatedType = 5
   couponBuyType = 6

 From typo3 backend => Commerce = Category I clicked in the tree at
Category => SYSTEM => COUPONS => syscoupons_use.
At the bottom (second last field) article_type_uid has the value
[ INVALID VALUE ("6") ]

So it seems that the relations are like this:
(TypoScript-variable = Article_type_uid = Article title)
couponNormalType  = 4 =	syscoupons		
couponRelatedType = 5 = syscoupons_special
couponBuyType     = 6 = syscoupons_use

Baed on this I changed the article to "syscoupons" in my test coupon, 
and now it seems to work - no ever increasing discount any more ;-)

As a side note: Should commerce_coupons create the 3 article types (4, 5 
and 6) that it expects, or should this step just be added to the 
documentation?
